What to check before you buy
- UL 2034 listing
- Residential CO alarms in the US are listed to UL 2034. Industrial CO monitoring is a different class of instrument with different alarm thresholds.
- Alarms expire
- CO sensors have a finite life - commonly 7 to 10 years from manufacture. Many units now sound an end-of-life chirp and cannot be reset.
- Placement
- CO mixes with air rather than layering at the ceiling like smoke, so alarms go on every level and outside sleeping areas. Keep them away from fuel-burning appliances and vents to reduce nuisance alarms.
- Digital display
- A display showing parts per million lets you distinguish a low-level chronic leak from a spike, which matters when talking to responders.

Frequently asked questions
Where should CO alarms be installed?
On every level of the home and outside each sleeping area. Because CO mixes fairly evenly with air, height placement is less critical than it is for smoke alarms - follow the manufacturer instructions.
How long does a CO alarm last?
The electrochemical sensor has a limited life, commonly 7 to 10 years from the date of manufacture. Most modern units chirp at end of life and must be replaced, not reset.
What CO level is dangerous?
UL 2034 alarms are designed to respond to rising concentration over time, sounding faster at higher levels. Any alarm should be treated as real: get everyone outside and call emergency services.
Is a CO alarm the same as a smoke alarm?
No. They detect entirely different hazards. Combination units exist, but a smoke alarm alone offers no protection against carbon monoxide.
Why does my CO alarm chirp?
A single periodic chirp is usually low battery or end of sensor life; a repeating alarm pattern is a CO event. Check the manual for the specific pattern before assuming it is a battery.
Where do the specifications on this page come from?
They are taken from the manufacturer's published listing. WC Safety does not laboratory-test products, and nothing is claimed here that the manufacturer does not state.
